Try as you might this holiday season to find the ugliest Christmas sweater imaginable, you're not going to be able to top YouTube's bd594's creation this year. It's got an ugly argyle pattern, a tacky Christmas tree, blinking lights, and the pièce de résistance?: a working toy train circling the gaudy creation.

There's no word on what this custom creation cost to build, but the look on your co-workers' faces when you show up to your company's black tie holiday party wearing this? Priceless. [YouTube via The Awesomer]
